Tamil Nadu’s third highest revenue-earning industrial cluster, after Oragadam-Sriperumbudur, and Coimbatore, is just 40 km away from Bengaluru. In fact, the balmy weather belongs more to Karnataka’s capital than to Tamil Nadu’s sweltering plains, even though there’s no discernable ascent in the terrain, or it’s so gradual that it feels unnoticeable. But the transformative effects of mechanisation are almost immediately apparent in Hosur, 35-year-old industrial cluster, and one that rose from a sleepy countryside of rocky terrain and small temples perched atop scattered hills.
